目的分析MSM人群HIV抗体阳性样本流行病学资料及蛋白印迹试验(WB)带型,为开展针对此类人群的防治措施提供科学依据。方法对某实验室2009-2013年确证HIV抗体阳性的MSM样本进行统计分析。结果 MSM人群HIV阳性者与总HIV阳性者相比具有年轻化、未婚者为主、文化程度较高、流动性大及职业以干职/学生/个体/自由职业者更多的特点,79.11%来源于自愿咨询检测,高于总阳性样本,MSM阳性样本WB带型与总阳性样本相比gp160、gp120、p24和p17差异无统计学意义,其余带型出现的频率低于总阳性样本,二者区别差异有统计学意义(P<0.05)。结论 MSM人群人口学特征显著,能主动寻求正规途径进行HIV检测,WB带型较总阳性样本具有早期感染的特征,该人群更早地检测出HIV感染情况,应针对该人群特点采取有效的干预措施。
Objective To analyze epidemiological data of HIV antibody positive samples and Western blot test (WB) genotypes in MSM population and provide a scientific basis for prevention and treatment measures against such population. Methods Statistical analysis of MSM samples positive for HIV antibody in a laboratory from 2009 to 2013 was performed. Results The MSM population with HIV positive was more younger than the total HIV positive, mainly with unmarried persons, with a high level of education, high mobility and more occupations with dry-service / student / individual / freelance occupations. 79.11% From the voluntary counseling and testing, higher than the total positive samples, MSM-positive samples WB bands compared with the total positive samples gp160, gp120, p24 and p17 no significant difference in the frequency of other bands appeared less than the total positive samples, The difference was statistically significant (P <0.05). Conclusion The MSM population has significant demographic characteristics. It can actively seek formal channels for HIV testing. WB banding has the characteristics of early infection compared with the total positive samples. The population detected HIV infection earlier and effective intervention should be taken according to the characteristics of the population Measures.
